Rapid Voltage Change
Rapid voltage change (RVC) is a quick transition of RMS voltage occurring between two steady-state
conditions, and during which the RMS voltage does not exceed the dip/swell threshold.
The threshold of RVC detection is configurable from 1 % up to 6 % of Udin.
The following data and values are determined during the evaluation of the rapid voltage change in SICAM Q100
and listed in the tab Rapid Voltage Change (see Chapter 8.4.2.1):
•
RVC event start time
•
RVC event duration
•
∆V
max
•

•
The affected phases (a, b, c, ab, bc, ca, a-b-c).
